Definitions

  • the present invention relates to the diversion of sheet material, particularly single or variable height stacks of loose sheets of printed paper, from a first path of movement onto a second movement path selectively and without a loss of alignment. More specifically, this invention is directed to apparatus for selectively engaging and guiding printed sheets out of the transport channel of a collating machine, along which such sheets are moving under the influence of pusher dogs, the intercepted sheets being caused to move along a surface that is inclined relative to the direction of motion established by the collating machine transport channel. Accordingly, the general objects of the present invention are to provide novel and improved methods and apparatus of such character.
  • the present invention is suited for use as a transferring-out facility wherein defective printed sheets or printed-sheet assemblages are removed from the stream of such sheets or sheet assemblages exiting a collating machine or the like.
  • Collating machines particularly in the book manufacturing industry, are provided with transport channels wherein the printed sheets are engaged by pusher mechanisms, known in the art as dogs, and caused to move in a first direction while being supported against an edge guide.
  • pusher mechanisms known in the art as dogs
  • 4,429,795 discloses a transferring-out facility of the type generally described above wherein defective printed-sheet assemblages are captured and ejected while the transport system of the associated collating machine is operating.
  • the transferring-out facility includes a driven conveyor which is angularly oriented with respect to an inclined collating machine transport channel surface.
  • An endless chain runs above the conveyor and supports a plurality of diverting pins which may selectively be caused to move between extended and retracted positions.
  • 4,429,795 is utilized for diverting very thin printed-sheet assemblages, such assemblages have a tendency to buckle while being guided to an upwardly inclined path defined by a conveyor, the thin printed-sheet assemblage moving in front of a pair of the diverting pins, and such bucking will lead to an interruption in operation.
  • the present invention overcomes the above-briefly discussed and other deficiencies and disadvantages of the prior art by providing a novel and improved technique and apparatus for guiding printed sheets from a transport channel, which defines a first path of motion, to a second motion path while preserving alignment to a high degree of accuracy, permitting high repetition rates and without subjecting the printed sheets to potentially damaging impacts along their edges or other unduly rough treatment.
  • the invention comprises a plurality of clamping systems which are arranged at equal distances from one another on axes which are perpendicular to the plane defined by the transport surface of the mechanism which is supplying the printed sheets.
  • the plural clamping systems are driven, by an arrangement of chains for example, such that they execute an orbiting movement in synchronism with the pusher dogs which cooperate with the transport channel of the supplying machine.
  • the clamping systems are supported and controlled such that they can be moved into the path on which the printed-sheet assemblages or individual printed sheets are moving so as to acquire assemblages or sheets which are to be transferred out of the movement path defined by the supplying machine transport channel.
  • the clamping systems because of their being driven in synchronism with the pusher dogs, arrive continuously at the path of motion of the sheets and, in part, extend through the transport surface on which the sheets are moving.
  • Each of the clamping systems is formed by a leading clamping device and a trailing clamping device and each of these devices is defined by a pair of cooperating plungers which act on axes which are perpendicular to the aforesaid plane.
  • the leading clamping device when actuated, acts on the printed-sheet assemblage or printed sheet in the region of the leading edge thereof while the other clamping device will act in the region of the trailing edge of the "work", the axes of the cooperating plungers of the leading and trailing clamping devices defining a plane which is transverse to the sheet or sheet assemblage and parallel to the lengthwise edges thereof.
  • the trailing clamping device will grip the printed-sheet assemblage or printed sheet adjacent the trailing edge thereof and in front of, and slightly offset relative to, the point of contact of the pusher dog which is propelling the sheet or sheet assemblage along the channel.
  • the drive arrangement for the clamping device typically a plurality of drive chains, defines a first track segment which runs parallel to the path of movement of the pusher dogs and a second or downstream track segment which diverges from the path of motion of the pusher dogs, the second track segment following an inclined transport surface upwardly at an angle.
  • the inclined transport surface is provided with an aperture which corresponds to the path followed by the clamping devices and the lower plungers of each clamping device extend through this aperture.
  • Apparatus in accordance with the preferred embodiment of the invention also comprises actuating means for the upper plungers of the clamping devices whereby these upper plungers can be caused to be extended into contact with the printed sheet or printed-sheet assemblage in synchronism with the continuously moving pusher dogs, the control means also resulting in the retraction of the upper clamping plungers at the end of the above-mentioned second track segment.
  • the present invention enables printed-sheet assemblages or individual printed sheets to be guided from a collating machine or the like that is operated in the high-output range, this guiding or transferring-out being accomplished with the assemblages or individual sheets being in a clamped condition.
  • the printed-sheet assemblages or individual sheets can be transferred to the transport system of another machine with their initial alignment preserved.
  • the present invention also, even at very high repetition rates, provides damage-free transferring-out, even if the printed sheets being processed are of very widely different sizes, and even if such sheets are very delicate.
  • FIG. 1 is a schematic top view showing of apparatus in accordance with the invention
  • FIG. 2 is a side elevation view of apparatus in accordance with a first embodiment of the invention.
  • FIG. 3 is a front view, partly broken away and interrupted, of the apparatus of FIG. 2.
  • a transferring-out facility in accordance with the invention would, by way of example, be installed in the delivery section of a collating machine.
  • printed sheets 1 stacked to form assemblages are commonly continuously transported forwards on a transport surface 3 while bearing against an edge guide 3a.
  • the transport surface 3 and edge guide 3a define a transport channel along which the sheets 1 are caused to move under the influence of pusher dogs 2.
  • the transport surface 3 is customarily inclined, as may best be seen from FIG. 2, transversely with respect to a plane of movement defined by the axes of the serially arranged pusher dogs 2.
  • the transferring-out facility is mounted on a machine frame in an inclined position determined by the angle of inclination of the transport surface 3.
  • the transport surface 3 defines a track segment A, wherein clamping devices 5 and 8, which will be discussed below, initially move in a direction which is parallel to the motion of the pusher dogs 2 at a defined lateral distance from the pusher dogs.
  • the transport surface 3 also defines a track segment B wherein the path of motion of the clamping devices diverges away from the path of motion of the pusher dogs.
  • the transferring-out facility comprises a plurality of clamping systems which are arranged at equal distances from one another. These clamping systems each comprise a pair of clamping devices which, in part, extend to the transport surface 3 and which are successfully guided into the path on which the printed-sheet assemblages are moving.
  • the axes of the clamping devices are arranged perpendicularly with respect to the transport surface 3, the clamping devices are caused to move in synchronism with the pusher dogs 2 and the path of motion of the clamping devices is determined by, in the disclosed embodiment, a drive system comprising endless drive chains.
  • Each of the clamping systems comprises a leading clamping device 5 and a trailing clamping device 8.
  • the leading clamping devices 5 include an upper clamping plunger 6 and a cooperating lower clamping plunger, indicated at 7a in FIGS. 2 and 3.
  • the trailing clamping devices each comprise an upper clamping plunger 9 and a cooperating lower clamping plunger indicated at 7b in FIG. 3.
  • the upper plungers of each clamping device are, when actuated, resiliently biased against a sheet or sheet assemblage which is thus captured between the upper and lower plungers of a cooperating pair.
  • the lower plungers of each clamping device extend through a longitudinal aperture 11 in the transport surface 3 and protrude slightly above surface 3.
  • the chain drive system of the disclosed embodiment comprises a plurality of chains which are led around direction-changing sprockets, the axes of rotation of the sprockets being oriented perpendicularly with respect to the transport surface 3.
  • the most inwardly disposed chains 21 and 21', with their respective sprockets 29, 29', are interconnected by means of guide profiles 27.
  • the upper trailing clamping plungers 9 are located within the guide profiles 27 and are supported in a manner which allows free-sliding displacement thereof.
  • the drive chain system also comprises a separate lower chain 42 which cooperates with sprockets 30.
  • Chain 22 carries the lower leading and trailing clamping plungers 7.
  • the sprockets 28, 28', 29 and 29' are mounted on common axles 24 while the lower chain sprockets 30 are located on axles 25 which are coaxial with axles 24.
  • the drive system of the present invention is operated in synchronism with the pusher dogs 2. All of chains 20, 20', 21, 21' and 22 are transversely and vertically supported on guide tracks as they move on their endless paths.
  • the mounting of the upper leading and trailing clamping plungers, respectively 6 and 9, from separate pairs of drive chains via guide profiles, allows the spacing between the plungers to be adjusted to accommodate different sizes of printed sheet.
  • the outside chains 20, 20' are detached from the drive and are shifted relative to the inside chains 21 and 21'.
  • the clamping plungers contact the sheet(s) along a line parallel to the lengthwise edges of the sheet(s). This is accomplished by causing the chains 20, 20', 21, 21' and 22 to initially run parallel to the path of motion of the pusher dogs 2 in the track segment A, the acquisition of the sheet(s) being accomplished during this time. The chains, and thus the clamped sheet(s), are subsequently led laterally away at an angle in the track segment B following the inclination of the transport surface 3.
  • the inclined transport surface 3, i.e., the surface along which the transferred out sheet(s) are directed, has a longitudinal aperture 11 which corresponds to the path followed by the drive chains.
  • the lower clamping plungers 7a-7e extend through and move along the aperture 11.
  • every clamping plunger is provided with a pressure surface which is comprised or coated with a non-slip material.
  • the upper clamping plungers 6 and 9 are mounted in respective guide profiles 26 and 27 so as to be moveable. This movement is necessary so that the upper clamping plungers may be raised and lowered as desired to capture a sheet or stack of sheets. Control over the extension and retraction of the upper clamping plungers is accomplished through the use of control rollers 31 which run on an orbital path 23 installed on the machine frame. The plungers 6 and 9 are held clear of the surfaces of the printed-sheet assemblages, i.e., are in the retracted position, while executing their orbiting movement.
  • Brackets 32 are located on the guide profiles 26 and 27, and brackets 33 are located on the clamping plungers 6 and 9. These brackets serve as attachment points for tension springs 10 which maintain the control rollers 31 in contact with the orbital path 23.
  • Mechanical switches 34 and 38 are installed in the orbital path 23.
  • the switch 34 is situated in the region of the parallel-aligned track segment A of the chain system.
  • Switch 34 is actuated by a cylinder 35 so as to cause the orbital path to be opened and closed.
  • the control roller 31 associated with the clamping plunger runs onto a descending control path 36, and the associated clamping plunger is thus moved toward the printed-sheet assemblage 1 through the agency of the force exerted by the tension spring 10.
  • the leading clamping plunger 6 will descend and clamp the sheet(s) between clamping plunger 6 and a selected lower clamping plunger 7.
  • the opening action takes place at the end of the track segment B in a manner similar to the closing action, by virtue of the fact that the control rollers 31 run onto an ascending control path 37 and successively raise the clamping plungers 6 and 9.
  • the opening action is accomplished by means of the switch 38.
  • Switch 38 is pushed aside by the ascending control rollers 31 and automatically recloses the orbital path 23 once the control rollers have passed.
  • the guide profiles 26 and 27 carry freely rotatable pressure rollers 39.
  • Pressure rollers 39 bear against raceways 40 formed in the machine frame.
  • the pressure rollers 39 provide support while the clamping plungers are applying a clamping force to a sheet or sheet assemblage.
  • the triggering of the mechanical switch 34 in order to actuate the clamping plungers 6 and 9, is synchronized with the motion of the continuously running pusher dogs 2. This triggering occurs, for example, after detection of a defective printed-sheet assemblage. It is to be noted, however, that the transferring-out facility of the present invention can be utilized for guiding a series of non-defective printed-sheet assemblages from a collating machine or the like, in which case the facility will operate continuously or, perhaps, in a preselected sequence such as alternatively.
  • the printed sheet or stack of sheets can be transferred onward from the apparatus of the present invention to another downstream machine. This further transfer is accomplished by means of a connecting conveyor installation 41 with pusher dogs 42. The sheet or stack of sheets bear against a guide 43 while on conveyor 41 and their alignment is thus preserved.
